Without a doubt, Sky lost the customer-focus (partly due to having no real competition for entertainment until around 2014/2015...and only beginning to have Sport competition now with Spark...).
By forcing a massive potential cohort of avid Spots fans to purchase other packages (that they don't really want) before they could add sport on has not proven to be a winning strategy in the long term (even though generous profits were generated in the meantime).
Amongst the questionable decisions, it's not all doom and gloom though. Sky has pumped a lot of money into local communities through various sports productions, created many jobs in NZ and has generated significant tax revenues to help our various governments meet their social agendas.
With a little luck, and a brand new focus on value delivery - I sure hope we can win you back RTM.
